a1, a screw rod (28) is rotated by bare hands, a first screw plate (212) can be adjusted in position along the axial direction of the screw rod (28), a rectangular transverse plate (211) can be driven to synchronously lift, an inverted door-shaped frame (21) is pulled to overturn around the rotating position by a first hinge plate (27), a door-shaped supporting frame (24) automatically overturns around the inner side wall of the inverted door-shaped frame (21) through a connecting seat (23) and a hoisting shaft (11), the hoisting height of the door-shaped supporting frame (24) is lowered, the door-shaped supporting frame (24) is always in a horizontal state, then a part to be assembled on the ground at the side of a conveyor belt is moved in from an opening of the door-shaped supporting frame (24) and placed on the inner bottom end surface of the door-shaped supporting frame (24), then the inverted door-shaped supporting frame (21) is reversely overturned, and the door-shaped supporting frame (24) synchronously rotates around the rotating position of the inverted door-shaped supporting frame (21), and in the process, the part to be transported in the hoisting of the door-shaped supporting frame (24) can be lifted;

a2, in the whole hoisting process, the parts to be transmitted on the ground are moved onto the conveyor belt to be transmitted without adding hoisting equipment, the situation that the workshop space is too crowded due to the fact that the hoisting equipment is added is avoided, the efficient operation of a workshop is affected, and the intelligent production efficiency of the railway vehicle is reduced.
